Answer:
To reduce a fraction: divide the numerator and denominator by their greatest common factor, GCF.
Fraction: 9/10 already reduced to the lowest terms.
The numerator and denominator have no common prime factors.
Their prime factorization:
9 = 32;
10 = 2 × 5;
gcf (32; 2 × 5) = 1;
Fraction: - 3/4 already reduced to the lowest terms.
The numerator and denominator have no common prime factors.
Their prime factorization:
3 is a prime number;
4 = 22;
gcf (3; 22) = 1;
LCM (10; 4) = 22 × 5 = 20
3/20 is the answer.........
